GAS-ENGINE.

Specification of Letters vPatent.

Application filed May 6, 1912. Serial IiTo. 695,371.

Be it known that I. Marinas \Vrissrn, a citizen of the United States.residing at Milwaukee, county of Milwaukee. and State of Wisconsin. haveinvented new and useful Improvements in Gas-Engines, of which thefollowing is a specification.

My invention relates to improvements in engines. and it pertains, amongother things.First. to the construction and relative arrangement of thepower cylinder, piston, valves and all the operative mechanism of theengine with the supporting inolosure of such parts, whereby suchsupporting inclosure is adapted to forma receptacle for a fluidlubricant, which lubricant, when placed therein, is caused bv themovement of the engineto be continuously splashed hv -the revolublemovement of the crankand otherwise conveyed to all of the moving partsof the engine. whereby the friction is diminished and the wear of theengine is reduced to the minimum. Second. to the relative arrangement ofthe power piston to drawn on line .'r.r of Fig. 2.

the inlet and outlet controlling valves, whereby the movement of one ofsaid valves is substantially counterbalanced by the movement of theother. and whereby the vibration of such valves is diminished. and,third, to the device for controlling the relative strokes of the outletand inlet gas controlling valves to correspond with the movement of thepower pistons.

Mv invention is further explauied by ref 7 erence to the accompanyingdrawings, in

Figure 1 represents a horizontal section Fig. 2 represents a verticalsection drawn on line yz of Fig. 1. Figs. 3 and 4 represent horizontaland vertical sections of a modified form of the engine shown in Figs. 1and 2.

Like parts are identified by the same reference numerals throughout theseveral views.

1 is a power cylinder into which the explosive gas led, compressed andexploded.

2 a power piston Wl11Cl1 is connected with the driving shaft 3 throughthe pin 4:, connecting rod crank pin 6 and crank 7 in the ordinarymanner. Gas is led to the valve chamber 8 through the inlet port 9, andit passes from thene into the cylinder 1 through the valve 10 and valveport- 11.

The valve 10 comprises the annular sleeve 12 provided with radial ports14.- and ceir tralpartition 13. The radial ports 1i connectwith thestationary annular channel 11 which connects with the cylinder 1 throughi the port 11, and said valve is adapted, with each reciprocatingmovement of the piston, to be brought into communication with the 'port11, leading to the cylinder. Motion'is communicated to 'saichjvalve 10fromt-he main driving shaft through the gear-15, indicated by dottedlines. in Fig. 2, gear 16, gear supporting shaft 17, crank pin 17, crank18, connecting rod lt), valve pin 20 and pin supporting lugs 21. Motionis also simultaneously communicated to the exhaust valve 22 from saidmain driving shaft 3 through said gear 15, gear gear supporting shaftQ-l. crank crank pin 26, connecting rod 27, valve pin 28 and pinsuppoi-ting lugs 29. and the relative size and position of said gearsand pistons to each;

other are such that the piston '2 is moved back. (reference being had toFigs. 1 and 2), in the'actof drawing gas and air' into the cylinder 1 asthe inlet port 11, leading to said cylinder, is opened, while the outletport 30. leading from said cylinder, is closed Patented J line 16, 1914;

by .said valve 22, whereby a partial vacuum is formed in the cylinder asthe piston is drawn back by the momentum of the fly wheel. not shown,whereby gas and air-are caused to enter said cylinder, as stated,preparatory to being compressed and. exploded. The relative size andposition of said gears,

pistons and valves to each other is such that inder through the duct 30,annular channel.

30 and thence inwardly through the'radial ports 32, from thence outthrough the center of the valve 22 and.outlet 31, when the. movementthus described will be again and continuously repeated. The outlet valve22 with radial ports 32 and the transverse partitlOIl 33. i

is a water jacket of ordinary construcr tion.

7 It will be understood that the engine thus far described is providedwith an 'ignitin'g mechanism of ordinary construction, which,

is connected with the operative mechanism of the engine in such a mannerthat a spark is produced and the gas is ignited at the proper moment assoon as the same is compressed by the forward movement of the pis ton,as previously described.

By the modified form of the engine shown in Figs. 3 and 4, twoadditional pairs of gears 36 and 37 are interposed between the gear 39carried by the main driving shaft 3 and the gears 40, 4.0 carried by thevalve actuating shafts 17 and 24, whereby the relative'movement ofthe'reciprocating valves 10 and 22 to that of the piston 2 is reducedand whereby said valves in said modified form are adapted to make butone stroke to every four strokes of the power piston, while by thepreferred form shown in Figs. 1 and 2, the gas controlling valves makeone stroke for every two strokes in the power piston. In all othermaterial respects, the modified form shown in Figs. 3 and 4 issubstantially the same as that shown in Figs. 1 and '2, and the severalcooperating parts are referred to by the same reference numerals. Toprovide 'forpacking the inlet and outlet valves and taking up wear, therespective valve chambers are made slightly larger than the valves,

thus providing for the reception of the pack ing sleeves 40, and saidpacking sleeves are each provided with a pair of resilient packing rings11, 4:1 which are retained in annular recesses-provided therefor in saidpacking sleeves upon the respective upper'and lower sides of saidannular channels. Saidresilient rings and said sleeve are respec tivelyretained in place by the annular sleeves 42, which sleeves are in turnretained in place by the heads 43 of said valve cylinders. It will, ofcourse, be understood that the resilient packing rings are adapted toform a tight joint between the inclosing bearings of the cylindricalvalves which they inclose.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isr In a gas engine, the combination with apower cylinder, two valve chambers connected with the opposing sides ofsaid cylinder, each valve chamber being provided with a packing sleeve,each packing sleeve being provided with an annular recess upon itsinside for the reception of a resilient packing ring, said ring bearinginwardly against the exterior surface of the valves, and an intermediateannular channel, one of said intermediate channels being formed for thepassage of an explosive mixture to said cylinder and the other for theescape of the burned products of combustion from said cylinder, a hollowcylindrical valve located in each of said packing sleeves provided witha plurality of radial ports adapted to communicate between the centralspace in said valve and the intermediate annular inclosing channel, saidvalves being also each provided with a transverse partition locatedbelow said radial ports and means for retaming said packing sleeves inplace between said cylindrical valves and the inclosing walls of saidvalve chamber, all substantially as and for the purpose specified.

in testimony whereof I affix my signature in the presence of twowitnesses.
